Re: Re: z/VM 6.1 under Hercules - How To

Part of the z196 implementation are a number of major changes with 
regards to specification of the architecture level set.  Embedded within 
these changes is the capability to manually adjust STFL/STFLE bit 
settings.  I believe the code is already in the SVN.  It is intended for 
just such situations.  Obviously, if you enable a setting for which 
Hercules lacks support and the program attempts to use is it, 
unpredictable results may occur.

If you're using the z/VM 6.1 Base system, follow/use the "Base" values below. If you apply the z/VM 6.1 RSU, then use the values on the left side.
